APPLICATION INFORMATION
DSP supply with sequencing
This application shows a power supply for a typical DSP. DSPs usually have core voltages in the 1-V to 2.5-V
range, whereas the voltage at the I/O-pins (I/O voltage) is typically 3.3 V to interface with external logic and
converters. Therefore, a power supply with two output voltages is required. The application works with an input
voltage in the range of 3.5 V to 6.5 V. The maximum output current is 150 mA on each output.
The supply is enabled by pulling the enable pin (EN of the TPS60503) to GND. The step-down charge pump
starts and its power good (PG) output goes high. This enables the LDO which powers the I/O lines and generates
a reset signal for the DSP. Figure 27 shows the timing diagram of the start-up/shutdown procedure.
